thereon, inthe manner or' a hammenhaving y an operating handle. In such stamps, it 1s desirable that there Vbe interposed between the 'handle and the stamping face means providing a suiiicient degree of resiliency adapting f the face of the stamp to effect good contact,

independent of variations in exact parallelthe stamping surface, when use The device consists generally of a stamp, in

either'singleor double formhaving an oper- "ating handle sol connected as to permit of a limited degree of flexibility whereby to com- I pensate for any lack 'of accuracy in delivering the' blow so as to allow the' stamping face to automatically adjust itself, under the impulse of the blow;

y In its construction, our stamp is composed of 'single or double head portions. composed of rubber or other suitable resilient or flexible gether with-detachable stamping' headsse- .cured thereto. Such heads are also of `rub-y 30 berl having on their faces any desired imi' printing' characters and are provided'with an inner reinforcing plate and securing'studs, [with certain other eaturesof' construction Y and advantage,

as shall be more fully hereinafter described. 5` A, The device is in its principal elements sim-` vilarj to thatshownin a companion applicationv iiled herewith i ferred constructions:

kunder side ofthe removable HAMMER.v STAMP i 192e. serial N0.e55,"1`24.

the stamp is inthe lform 'ofa'main hammer head 2 of rubberor the. like-having an enlarged outer body of circular or other form vadapting it to receive andbe secured to the detachable stamping head'2b. stamped and The body` portion of the head Qvmay be of innert diminishing or' narrowed neck 6 having a iiat opposing face for. attachment to and connection with the end 7 of an operating handleS.. A central connecting bolt 9 is irri-' bedded and vulcanized by its head and shank .portion within'the middle of oneof the heads `21and. projects suiliciently far beyond its Vsmaller attaching face to extend'through a registering hole in the end of the handle and therebeyond, -for attachment to the companvvion head 2a at the opposite side, as in F ig. 4. material, a handle andy meansV connecting it i with the stamping member or members, Ytobut is providedwitha centrally imbedded 'fand vulcanizedrsleeve nut 11l ofany suitable form.; l v

Thel nut All makes screwengagement with the threaded outer end'of boltr 9,'by turning and tighteningv thereon, :by which 'the twoV heads are tightly ,clamped together and against the opposite sidefaces of the handle PATE-Nr j Fries v.any suitable form, and is provided'with' an in such construction'theopposite head 2a `1s generally similar tohead '2 abovedescribed, l

terminal 7.V By 'such construction head 2a f may be readilyA c onnectedfto or disconnected' from the other head 2,'i`or substitution asv to one or ibothQoi other similarheadsof dif-3 Y i .35.,

ferent site or `for any other purposefl Byg such construction'- the', comparatively softrv rubber body fof the-heads; surrounding theboltand nut respectively ,provides ample y flexibility `to adaptthe 'face of; eithersupplementalstamping headZbftomake afgood stamping impression, whether brought. fairly and evenly against the surface to be stamped, or at a considerable angle thereto by the operator. Y

Vhen there is any such variation and the face of either head is brought against a surface with which it would not ordinarily register, due to any angular relation, the iexibility of the head connection with the handle permits of automatic adjustment and good stamping results, under impactof the blow. y i

The supplemental stamping head2?) at either side isprovided with any suitable printing letters, figures or characters, as indicated on 'the faceviews, Figs. 2 ande3`. Such characters areordinarily molded in the rubber,'as at 3, or may 'be in the form; of detachable inserted type 4f, allmounted on a common plane. y

y'For thepurpose of reinforcing the head 9.?)

i closely adjacent to the area embodying such ing heado is that it may be readily bent to ,a concaveform for attachment to the convex Y characters, and 4for pro viding a substantial attaching base, the head 2?) is provided with a thin reinforcing disk or plate 5. kSuch plate is tightly secured to the inner face of head 2?) by anysuitable means as cementing, vul-` canizing, etc., and may be of suitable material, as brass.

Heads 2 and 2a are eachprovided with transverse reinforced bolt holes having inserted tubular lining sleeves 13 extending hrough from one side to the other, and vulcanized tothe rubber, asin Fig. c

Head 2b is provided with a corresponding series of similarly located and spacedcon-VV necting bolts 14 having VenlargedY reinforcing beveled heads 15, the fiat inner ends of which are soldered or welded to the face of plate 5. The outer endsof sleeves 13 are inwardly beveled to receive heads 15, so that when the stampin" head 2b isvin aosition the )arts `fit lsnugly Vandtightly together, and are held by the securing nuts 16.

One advantage of the comparatively thin plate 5- when tightlysecured to the stampface of the main head orbase, as making a rocker stamp, capable of rolling motionover the surface beingstamped.

By such construction it will be seen thatV a f,

. supplemental head Vmay be substituted for another ateither; side, having anysuitable or different form, kind,V or arrangement of stamping characters, either molded'in the rubber facefof the head itself, or separately attached as vvby the stampingchara'cters 4a.

The latter -mayr be, of .the split wedge type like that shown in priorpatent ofWV. J. Palmier, Jr., '1N o. V1,191,820. In suchy case i .their divided bases bear against the inner y toplate 5,providing a suiiicientlyjfrm and lcomparatively,'rigid opposing bearing.;

socketed'surface of the head, closely adjacent to be marked, without the necessity for anyspecial skill.

lIt will be understood that one of the heads,v as 2, alone may be used without the other by connecting its bolt 9 with the handle8 byse.z

curing nuts, asin Figf of our companion application Ser'. No. 355,123, filed herewith.

Also that the material of thesupplemental head 26 may be of rubber, metal, or any other suitable material.

The device is extremely useful, very durable, and may be made in different shapes, designs, sizes, weights, or otherwise changed or Y' varied by the skilled mechanic, but all such changes are to be understood as within the scope of the following claims. i

hat'we claim is: 1. The combination with a resilient headV having a ilatouter facerand a series of` bolt openings having sleeve,linings'thereim of a separable stamping head provided with a base plate secured to the` inner face of the headV and bolts secured tothe plate and extending through the bolt hole-linings.

2. The combination'with a resilient head having a flat outer face and-a series -of bolt openings having sleeve linings therein inrable stamping headprovided with a'base plate secured tothe innery face of the head and bolts' having beveled heads secured to thev plate having interiitting engagement withV vwardlybeveled at their outer ends,` of a sepaporting head having an inner. handle attach-v ing neck and an outer-enlargedk flat vface portion, of a separable'stamping headprovlded .with an inner lixedly attached base plate havingv connecting bolts extending through the yflat face i portion securing thestamping head thereto. Y l f 5. The combination witha holding handle having a perforated flat `face terminal, of a hammer stamp 'comprising a resilient head Vhaving'an inner integral flat end neck engaging the handle terminal and alaterally enlarged flange-like basehaving bolt openings therethrough, and a'stamping head provided with holding bolts extending through and secured. -inithe bolt openings. n

6. The combination with ajliolding handle iso'k w having a. perforated flat face terminal, of a p hammer stamp vcomprising a vresilient head i bolts extending throughand secured in the 'Y bolt openings.

In testimony' whereof We hereunto aX our signatures.
